52 The Control of Mosquitoes 



found on the screens between 9 A.M. and dusk. 

 When Anopheles in buildings are trying to find 

 openings in the screens of windows or balconies 

 they are not easily frightened and are readily 

 captured. They are so persistent in seeking an 

 opening that it is necessarj'^ to alarm them several 

 times before they will leave the screening. 



When such extensive topographical changes 

 were made that it was tem.porarily impossible to 

 control the increased influx of mosquitoes at a 

 camp, the laborers of the oiling brigade destroyed 

 mosquitoes found in barracks in the early 

 mornings.
